Unusual weather

Send your pictures to Les Cowley, I'm sure he'll find the inner circle interesting.  I was also thinking that the inner circle was a bit colourless.  I've never seen a circle like that. How uncommon really depends on your location.  I would say that the 46° is pretty common in Scandinavia during win...

Unusual weather

Nice.  I think you identify correctly.  I haven't seen a complex display here at this time of year, but in winter when the ice crystals are at "ground level", the halos and arc can become very bright, even the rarer ones. As for the smaller, inner ring, I am not sure.  My immediate thought...

33689  It's not like nuclear radiation which may make things radioactive. Yes, but usually, what makes people or things radioactive is the contamination by radioactive dust or material, not the radiation itself.  For that, the radiation needs to change the nucleus of atoms to form new isotopes.  Ne...

Coronavirus (COVID-19) Thread

The app that was launched in Norway a month ago does pretty much exactly the opposite: gathering GPS data, storing everything centrally, closed source, and if the app is activated, the battery drains in no time.  Thanks for the effort, but no thanks.  The approach explained in the video isn't waterp...

33605 their response will be critical just as the shutdowns in the big cities were. Rural areas can surely do fine with limited shutdowns, however.  Strict shutdowns are only meaningful in densely populated cities.  The Norwegian "shutdown" was limited to a few businesses (dentists, haird...

Unusual weather

Oslo this morning.  It's the fourth time over the past two weeks we've woken up to this, and we've had more snow in May than we had in the whole of January and February put together this winter.  I was making jokes about exactly this in late February when we hardly had any snow.

I tried to look for the age distribution for US covid-19 deaths, but could not find any recent data.  Whether that looks similar to Scandinavian corresponding data could indicate how well other data data can be compared.

33519 What does this imply for Sweden?  If the strain of the virus spreading there has a similar mortality rate as in New York, for which let's use the 0.55% figure, then their 2152 deaths (according to worldometers as of this writing) implies they have had 390,000 true infections so far. Not milli...

33493 Did you see how he mentioned (on Earth Day) how the highest rates of it are in highly polluted areas, where the asthma rates are 3x worse?  Very much on point and exactly why we need tougher regulations. The correlation may simply be that both pollution and virus spread are correlated with po...

I watched it through binoculars last night, but didn't bother to rig up anything for photography.  The weather was very good, and I'm glad I remembered to look for it.

Tests in Iceland indicate that half of those infected are asymptomatic, but  this study indicate that as many as 80% are asymptomatic .  If that's really true, lockdowns wont do much. I'm somewhat skeptical.  But maybe there are different mutations with different percentages.  Over here things explo...

33276 Just a personal thing, I find that very hard to believe. Everything about this and the situation is very suspicious.  Pandemics happen from time to time, why should it be suspicious?  It's only 10 years since we had the swine flu.  Covid-19 and the swine flu differ in some way.  Covid-19 spre...

33250  was under the impression that the views had changed.  If a virus can mutate and evolve then it should be considered to be alive. I lean towards not.  They're more chemical parasites.  Your definition is too wide.  You can write a computer program introducing random mutations to an initial st...
